Question

The form looks like this:

 <form action='localhost/test.php' method='post' target='test'>
 <input type='text' name='add_to_url' value='' />
 <input type='submit' name='submit' value='Go' />
 </form>

And I can’t get anything to even come close.

Ideally the bookmarlet would use the current webpage URL as the add_to_url value, and then submit the form.

Any leads?

To get the url of current page you need to use location.href Javascript property.
